How much power can the calories comparative h beam rods and gm crank hold on and F1r looking to go about 1100 can these take that kind of abuse

Callies rates there H beam for 750 I think. I beam compstars have been known good to around 1100 rwhp. I have a set of I beam compstars in mine

I would upgrade to a Callies ultra rod and a Magnum crank to make a real 1100hp on a blower car.

That's kind of what I expected any of you guys had any experience with Howard's billet I beam rods

I am running the Callie's ultra billet I beams on a magnmum crank, I would not attempt it with the cheaper H beams especially if you plan on turning it up and high RPM.

if your going to run that f1 to that power level you should look in to a aftermarket crank. turbo cars can get away with more power from the stock crank then a procharger

I agree with most of the opinions expressed if it were a turbo car things would be different I made north of 1100 rwhp through an unlocked auto with the callies H beams and a stock crank but I also did bend one at less power.
